Abstract
A cationic collector comprising a compound of the formula (I)
) Imidazoline quaternary ammonium salt compounds are shown. The invention also discloses the application of the cationic flotation collector, which is prepared by mixing the formula (A)
Description
Technical Field
The invention belongs to the field of beneficiation reagents, and particularly relates to a cationic flotation collector and application thereof.
Background
The cation collector is an important mineral dressing agent, after reverse flotation desilication of iron ore is successfully realized by taking fatty amine cation as the collector in the United states, the cation collector also realizes flotation desilication impurity removal in bauxite, phosphate rock and other ores, and is industrially applied to sylvite flotation and zinc oxide flotation. Fatty amine is still the most common cationic collector so far, and is characterized by small dosage of medicament and simple process flow. However, the aliphatic amine is insoluble in water, needs to be prepared by adding acid when in use, is particularly sensitive to slime, foams easily run out of a groove, and has poor selectivity, so that the aliphatic amine collecting agent cannot be widely used in industry.
In order to solve the problem of the aliphatic amine collector, chinese published patent document CN103769307A discloses a water-soluble cationic collector. U.S. published patent document US3960715 discloses a method for reverse flotation and desiliconization in iron ore by taking a dodecyl trimethyl quaternary ammonium salt compound as a collecting agent. Chinese published patent document CN 106238215a discloses a novel quaternary ammonium salt cationic collector containing multiple hydroxyl groups and multiple amino groups, which can be used for reverse flotation desilication of collophanite. Chinese published patent document CN102698876A discloses a cationic collector mainly composed of alkyl poly-amine ether, which has a good effect in reverse flotation desilication of iron ore. The cationic collectors disclosed in the above patent publications are all improved compared with aliphatic amine collectors, but have certain disadvantages, and in the flotation of silicates with a large number of fine particle sizes, foams are sticky and the sorting property needs to be improved.
Imidazoline quaternary ammonium salt is a novel high-efficiency cationic surfactant developed in recent years. The molecular structure comprises a nitrogen-containing five-membered heterocyclic ring, alkyl hydrophobic branched chains and hydrophilic branched chains with different carbon chains, and polar heteroatoms such as nitrogen and oxygen on the heterocyclic ring, wherein lone pair electrons on the outer layer of the nucleus have the capability of providing electrons for a metal d track, and a stable compound with a feedback bond structure can be formed through a reverse bond track. If the molecule contains benzene ring, the big pi bond contained on the benzene ring has pi electrons and can enter the empty d orbit on the metal surface, and the anti-pi orbit simultaneously accepts the electrons of the d orbit, the formed feedback bond can generate multi-center chemical adsorption and can be stably used in acid, neutral and alkaline media. At present, imidazoline quaternary ammonium salt compounds are widely used as corrosion inhibitors in the petroleum industry and also applied to the industries of plastic processing, printing and dyeing, leather, medical treatment and health care and the like, but the imidazoline quaternary ammonium salt compounds are not reported to be used as flotation collectors in the field of beneficiation reagents.
Disclosure of Invention
Aiming at the defects of the existing cationic collector, the invention provides the imidazoline quaternary ammonium salt cationic collector which is used for flotation of silicate minerals or flotation of sylvite ores.
The technical problem to be solved by the present invention is achieved by the following technical means. The invention relates to a cation type flotation collector which is characterized by containing a formula (I)
) Imidazoline quaternary ammonium salt compounds shown:
in formula I:
R1is C4-C20An alkyl, alkenyl, cycloalkyl or aryl group;
R2is H, CH3、CH2COOH、CH2COONa or C6H5CH2；
R3Is a polyamine ethyl or hydroxyethyl group;
x is F, Cl, Br or 1/2SO4 2-。
The invention also discloses the application of the cationic flotation collector, which comprises the following steps: the application is represented by the formula (A)
) The imidazoline quaternary ammonium salt compound is used as a silicate collector or a potassium salt flotation collector in oxidized ores. Formula (A), (B) and
) The imidazoline quaternary ammonium salt compound is mainly used as a collecting agent for removing silicate impurities in the reverse flotation desilication collecting agent in iron ores, phosphorite ores and bauxite by reverse flotation, or is used for separating potassium chloride by flotation of potassium chloride collecting agent in potassium ore flotation. Formula (A), (B) and
) The imidazoline quaternary ammonium salt compound is used as a collector alone or in combination with other mine collectors. The other mineral collectors are selected from one or more of fatty amines, ether amines or alkyl quaternary ammonium salts.
The imidazoline quaternary ammonium salt cation collector has the advantages that the molecular structure of the imidazoline quaternary ammonium salt cation collector has the nitrogen-containing five-membered heterocyclic ring, and lone pair electrons carried by the outer nuclear layer of polar heteroatoms such as nitrogen and oxygen on the heterocyclic ring have the capability of providing electrons for metals, so that the imidazoline quaternary ammonium salt cation collector has better selectivity than fatty amine. Compared with fatty amine, the collector provided by the invention is convenient to prepare, can be directly dissolved by adding water, can quickly eliminate foams during flotation, and also has the advantages of strong collecting property and good selectivity.

Example 9 flotation collector flotation test comparative experiment example 1:
single mineral flotation tests were carried out on pure minerals of quartz, kaolinite, montmorillonite and micaceite using SCI-12, SCH-18 and dodecylamine as collectors. In the flotation test, the pH value of the ore pulp is about 9, the concentration of the collecting agent is 350mg/L, and the flotation results of different collecting agents are shown in table 1. As can be seen from table 1, the flotation recovery rates of the two collectors of the present invention for quartz, kaolinite, montmorillonite and micaceite are superior to those of the traditional collector, dodecylamine.
